CHICAGO, ILLINOIS, A CORPORATION OF ILLINOIS SHOE VAMP margarine Mndm Application filed November 2 0, Serial No. 496,899.

This invention relates to improvements in shoe vamp treating mechanism.

The principal object of the invention is to provide a device for stretching or deforming the vamp of shoes, particularly such as ladies strap slippers or pumps, in cases where the vamps bear too tightly against the wearers instep. At the present time there appears to be no very satisfactory method employed by shoe retailers to correct this common difficulty. In some cases it is necessary to cut away a portion of the vamp to avoid the pressure on the instep and in other cases a last is inserted in the shoe and the entire shoe is stretched. Frequently the stretching of the shoe by a last, although it may relieve the pressure on the instep, is objectional since the fit of the shoe as a whole may be rendered too loose.

Another object of the invention is to provide a machine which is portable and which can be clamped to a convenient support, such as a shelf, table, counter or the like, and is provided with a pair of relatively adjustable vamp treating rollers which enable the operator to stretch the vamp in such particular portions thereof as may be necessary in each instance and to the desired extent.

Other objects relate to various features of construction and arrangements of parts which will be apparent from a consideration of the following specification and accompanying drawings, wherein:

Fig. 1 is a side elevation of a machine embodying the present improvements;

Fig. 2 is a broken sectional view taken on line 22 of Fig. 1; I

Fig. 3 is a broken sectional view taken on line 33 of Fig. 1.

In the drawings, 10 indicates generally a frame having a clamping screw 11 at its lower end whereby the machine can be removably secured to any suitable support, such as the edge of a counter, table, bench, shelf or the like. Extending laterally from the standard 12 of the frame is an arm 13 provided with two uprights 14 and 15 which are connected by an upper portion 16. The frame preferably is a casting although not necessarily so.

J ournaled in the uprights 14, 15 is a shaft 17 having a bell shaped roller 18 secured at one end thereof and. a' gear 19 at the opposite PATENT:

OF CHICAGO, ILLINOIS, ASSIGNOR 'ro veMP-nAsEnicomrAnY, or

end. The shaft 1? "is held against lateral movement by any approved means such as by stops 20, 21', which may be secured to the shaft by setscrews 22. p The upper portions of the uprights 1 1 and 15 are provided with recesses 23, 24, respec tively in whichare positioned bearings 25, 26.' A second shaft 27 is journaled in-the bearings 25, 26, .and held against lateral shown, the adjacent end of the shaft being provided-with a handle or crank 31 for r0- tating or oscillating the shaft. The other end of the shaft 27 is provided with a roller 32 of a shape complemental to that of the roller 18.

The bearing block 25 is vertically slidable within the'opening 23, a spring 33 being provided which tends to press the block upward- 1y or in a direction to move the roller 32 away from the roller 18. A screw 34, extending into the recess 23 is arranged to bear against the bearing block 25 whereby the roller 32 may be-adjusted relatively to the roller 18. To permit this movement the bearing 26 is pivotally mounted in the recess 2 1 by means of screws 35, for example, the mesh of the movement by stops 29. A pinion 30 is fixedto the shaft 27 in mesh with gearl9, as v of the shaft 27. The pivotal axis of the shaft27 being relatively close to the pinion 30, adequate movement of the roller 32 can be effected with relatively small arcuate movement of the pinion.

In'use the vamp of a shoe is inserted between the rollers 18 and 32, the tightening screw 34 is rotated to tighten the rollers on the vamp and the handle 31 is then operated. Usually the handle action will be oscillatory to move the vamp back and forth between the rollers to stretch or deform the vamp sufiiciently in the desired portion to relieve the pressure upon the foot. During the operation of the handle the rollers can be gradually tightened upon the vamp, by means of screw 34:, until the desired result is obtained. The shape of the rollers is such, as will be seen, that the edge of the Vamp will be stretched or turned upwardly, with reference to the shoe. A shoe 36 positioned in the machine is indicated fragmentally 'by dotted lines in Fig. 1.

Although I have shown and described an embodiment of the invention for the purpose of illustration, I do not wish to be restricted specifically thereto except as so limited "by the appended :claim. 7

I claim:

A machine for operating on shoe Vamps comprising a support, a pair of rollers ro- V tatably mounted thereon, one of said rollers increasing in diameter "by unequal increments from the outer to the inner end thereofto provide an outer surface centrally concave in cross-section and terminating at its inner end in a peripheral extension, said other r-roller being shaped for pressing the, vamp into the concavity of said first roller and against the outer face of said extension, means for rotating one of said rollers, and means for varying the pressure of said rollers on a amp positioned between the same.

In testimony whereof, I have subscribed my name 7 AUGUST ROST.
